To all whom it may concern:

Be it known that 1, TBA l t/BUCHANAN, a citizen of. the United ,7States, residing at Yelm, in the countyofsThurstonand State ofWashington, have inventedcertainanew and useful Improvements inValve-Lifting object to provide a simple and easilyvapplied device forthe purpose of compressing the valve spring and allowmg the valve tomove downwardly to its open position so that itmay beeasilyicleaned-orremoved for the purpose of regrinding the valveand itsseat. it i It is another important object of the invention to provide adevice for the above purpose which is so constructed that bo-th hands ofthe mechanic are free, whereby the Work may be greatly expedited. 1M1 IIt is alsoone of the detail olojeets of the invention to provide a valvespring lifting lever, and an adjustable fulcrum tfo-rsaid lever,Wherebyitanay be operatively applied to motor valves having stems ofvarious lengths.

With the above and other objects in view,

the invention consists in the improved construction, combination andrelative arrangement of the several parts as will be hereinafter morefully described, subsequently claimed and illustrated in theaccompanying drawing in which similar reference characters designatecorresponding partsthroughout the several views; and wherein- Figure 1is a side elevation showing one embodiment of my improved tool asapplied in practical use;

Fig. 2 is a section taken on the line 22 of Fig. 1;

Fig. 3 is a plan view of the foot plate of the lifter; and

Fig. f is a detail perspective view of the adjustable fulcrum plate forthe lever.

Referring in detail to the drawing, 5 'designates a vertically disposedbody bar having a laterally off-set portion 6 formed with alongitudinally extending slot 7 therein. To one end of this bar, ahorizontally dis posed handle 8 is integrally connected. The other endof the body bar is curved, as shown at 9, and is formed with a graduallywiden- Pate ted June 24, 1919.

iingr"horizontally disposed foot plate 10.

.iThis 110013 plate at t its extremity recessed, .las-zatzll, and formedwith a countersink 12 attthe ledge of saidmrecess, which is adapted toreceive the lowervalve spring Washer. Thus; lateral shifting movementof: the awasheriplate and its frictional contact with the valve stem 5or a. rod will "be prevented.

lever l3lextends through the slot? of the i'bod-y bar Stand is fulcrumed1 upon a I pin F15: conn-ectingithe arms of a bifurcated plate 14,Xbetween which :saidlever extends. A i. ilhOlilli 161 hasr its headedend engaged 1 in the slot 7 and extends through anopening in theopposite end of the plate 14 and through a "reoinciding :opening'inthewasher 17 which is interposed betweensaid plate andthe side '1 ofthebody bar 5. A clamping nut lS of any suitalble type is threaded upon theother end 0f. SELlClllflJOlh to: securely clamp the plate 1 1 .ill'ljitsadjusted position upon the body bar. :adijusting said plate, itwill-be readily understoodthat the fulcrum 15 for the lever may bedisposed at the requisite distance ifromthe fo ot=plate12so that" theend of the lever13ican e properly applied to the valve springs: j j

iAiring or link 19 is permanently engaged in an eye 20 on the end of thehandle 8. T-hedistancebetweenthe fulcrum 15 andthe bolt lo is such thatin any adjustment of the plate 14 upon the 'body bar, the lever 13 isnormally disposed at such an angle relative to the handle 8 that the endthereof, corresponding to the end of the handle provided with the link19, is disposed an appreciable distance below said link.

In the application of the device, it will be understood that the footplate 10 is operatively engaged with the lower valve spring washer, asabove explained, and the lever 13 properly adjusted so that its shorterend will extend above the valve stem. The operator now forces theopposite end of said lever toward the handle 8 so that the valve isforced downwardly and the spring compressed. The ring or link 19 is thenengaged over the end of thelever 13 so that both hands of the mechanicwill be free for the purpose of grinding the valve face or its seat. Thedevice may be very easily and quickly removed to permit the return ofthe valve to its normal position 'by simply disengaging the link fromthe end of the lever 13.

From the foregoing description, taken in connection with theaccompanying drawlng, the construction, manner of operation and severaladvantages of the device Will be clearly and fully understood. Theseveral parts of the invention are all of very simple and durableconstruction and can be easily and quickly assembled or disassembledlOwing to the provision of the adjustable fulcrum for the valve liftinglever, the device can be readily applied to different types of motorvehicle engines. In view of the simplicity of the construction of myimproved valve lifter, it Will further be appreciated that the devicecan he manufactured at relatively small cost.

While I have herein shown and described the preferred construction andrelative arrangement of the several parts, it is to be understood thatthe device is susceptible of considerable modification and I,accordingly,

reserve the privilege of adopting all such legitimate changes as may befairly embodied Within the spirit and scope of the invention as claimed.

I claim 1. A valve lifting tool including a body bar having an angularintermediate porbar having an angular intern'lediate portion and a footplate extending in one direction from said intermediate portion recessedto receive the valve spring Washer, a handle extending in a relativelyopposite direction from the intermediate portion of the body bar, saidmedial portion of the body bar having a slot therein, a valve springcompressing lever extending through said slot, a fulcrum for said levermounted upon the body bar, and said fulcrum being provided With meanswhereby said fulcrum may be adjusted to position the same relative tothe foot plate.

3. A valve lifting tool including a body bar having an angularintermediate portion and a foot plate extending in one direction fromsaid intermediate portion recessed to receive the valve spring Washer, ahandle extending in a relatively opposite direction from theintermediate portion of the body bar, said medial portion of the bodybar having a slot therein, a valve spring compressing lever extendingthrough said slot, a bifurcated plate arranged on one side of the bodybar, a fulcrum pin for the lever connecting the spaced arms in saidplate, and a clamping bolt for the plate adjustable in the slot of saidbody bar, whereby the fulcrum of the lever may be positioned relative tothe foot plate.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
